m A further object is to provide a scouring pad holder made up ofwoodand a piece of spring steel wire, bent in :such a form, that thepoint of thehook end of the wire, will be directed downwardly at anangle, for-readily forcing the said point into the pad, without touchingthe pad vwith either hand, and when pushed up against the holder byforcing the handle down, to have the hookturnto compress the pad upagainst the handle, and at the same time lock the wire in thisup-position. Y r a I With these and other objects, my invention residesin certain construction, oneembodiment of which is illustrated-in thedrawings, wherein like figures of reference refertol-ike parts, ishereinafter described, itsop'eration V i The wire 21 has two longportions 27 and 28,

is explained; and what 'I claim is set forth. In the drawings, I 1Figure 1 is a side elevation ofa scouring 30. device embodying myinvention, and is shown partly broken away to illustrate the internalconstruction. p

Figure 2 is a bottom plan of the device shown in Figure 1, illustratinga fragment of circularsteel wool .pad attachedto the holder. r

Figure 6 is in Figure 4.

a top plan of theholder shown In the figures, the circular handle 10,preferably made of wood, is shown to have a central long bore 11,opening belowinto a shallow circular pocket 12, concentric there.-

-to and, greater in diameter than the bore. 11.

The bore 11 opens above into a cylindrical pocket 13, concentric with,but of greater diameter than the bore 11. This pocket 13 opens aboveinto alarger pocket 14 concentric thereto, and in the top of the holder.A conis cal shoulder 15 is formed between the bore 11" and the pocket13', while a conical shoulder 16 r is formed between thepockets 13 and14;. The handle 10 has a spherical body 17, terminatingin a neck 18,below which is a flared shoe portion 19 in which is the shallow pocket12.

About the. neck 18, is the flexible shield 20, which may be of sheetrubber, cloth or any other suitable material.

A wire member 21, is formed to function with the bore 11, the shoulders15 and 16 and the pocket 12. This member 21 is made of a single piece ofspring wire, with a loop 22 at thetop, and is bentto form a heel 23. The

loop 22 is firmly fixedin theslot 24, 0f the cap.

25, and is further secured by a cross pin 26.

integral with a central loop 29. The upper part of the portion 27terminates. inthe loop 22, while the lower part of the portion 28terminates in a straight long pointed hook 30,

. in Figure 1, the wire member 21 is shown in a strained or-forced bentposition with the portions 27 and 28 nearlyparallel. The circularscouring pad is marked 33.

VV hen assembling themember 21', with the handle 10, having the cap 25,of adiameter adapted to slide intotheborell, the cap. 2 5.

is moved up into thejbore 11, until the hee122 engages the conicalshoulder 15. At the same time, the portion 28 bears against the innercircular edge 34, of the pocket 12, and the loop 29 bears, in theopposite direction, against the wall of the bore 11, causing a forcedbending of the member 21, that decreases the otherwise normal,unstrained, angle between the portions 27 and 28.

With the pad 33 resting on a firm surface 35, (see Figure 4) and thepoint 31, of the hook 3O placed a little back of the center of the pad33, the handle 10 is firmly gripped by one hand of the operator andpressed down, while the fingers touch the top side of the shield 20. Thehook 30 is thus imbedded into the meshes of the pad 33, and as the point31, of the hook 30, bears against the hard surface 35, the member 21 isshoved up into the bore 11 and the pockets 13 and 14. The heel 22, atthe same time, travels up and snaps over the upper shoulder 16, due toflexed action occurring in the length of the member 21, as the portion28, moves up as it bears against the edge 34, straightening out themember 21, putting the same in a strained spring condition, whereby thestrain comes in connection with a bearing point at the wall of thepocket 14 and a bearing point at the edge 34:, both these bearing pointsbeing on one side of the member 21, and an intermediate bearing point ofthe central loop 29, against the wall of the bore 11 on the oppositeside of the member 21, as shown in Figure 1. Ihe hook 30 then becomeshorizontal, drawing the central portion of the pad 33 up into the pocket12, compressing the steel wool of the pad up against the inverted bottomof the pocket 12, as shown in Figure 1.

To release the pad, the cap 25, in the pocket 14, is pressed radiallyinward to dislodge the heel 23 from hooked engagement with the conicalshoulder 16, and then is pressed downward into the pocket 13, until theheel 23 engages the shoulder 15, and the hook 30 points downward at theangle shown in A Figure l, when the pad 33 can be easily released.

IVith the heel 22 engaging the shoulder 15, the member 21 is preventedfrom falling out of the handle 10. While the member 21 is of a singlepiece of wire and is easily formed, the functioning of its parts, intending to resume their normal positions with respect t2 one another,when sprung from their angular relation, during a longitudinal moven entwithin the handle 10, effects the desired releasable attachment of thepad 33 with the handle 10 in a quick and practical manner withouttouching the hand to the pad 33. The flexible shield affords protectingmeans to the lingers either when operating on an extended surface or thesurface of a thin cylindrical object like the handle of a tea pot ormetal cup, in which event the pad is bent around the object beingcleaned.

While I have illustrated and described but one embodiment of myinvention, changes therein can be made without departing from the spiritand scope thereof, I therefore wish to include all forms which comewithin the purview of the appended claims.

I claim,

1. A scouring device comprising a pad, a handle having a hole axiallypositioned therethrough, a shoulder on the wall forming said hole, abent wire member laterally sprung within said hole, a heel portion atone end of said member and a hook portion at the opposite end thereofextending beyond the lower end of said hole, with the point of said hookbelow the transverse plane of said lower end ofsaid hole, projectingoutward with respect to said hole, said heel portion being 0 adapted forreleasable engagement with said shoulder.

2. A scouring device comprising a pad, a handle having an axial holetherethrough, a spring wire member adapted for manual reciprocationwithin said axial hole, a shoulder on the wall forming said hole, saidmember comprising a heel portion at its upper end adapted to engage saidshoulder, a hook portion at its lower end extending below said hole andaway therefrom and a loop portion intermediate of the ends of saidmember, said member being sprung within and across said hole to havesaid loop in sliding spring pressed engagement with the wall of saidhole, whereby said heel is adapted to snap onto said shoulder, and saidhook is given an angular movement when attaching said pad to saidhandle.

3. A scouring device comprising a pad, a handle having an axial holetlierethrough, a shoe portion at one end of said handle, a shallowpocket in said shoe portion co-axial with said hole, two shoulderslongitudinally spaced on the wall of said hole, a wire member having aheel portion at its upper end, and a hook portion at its lower end forengaging said pad, said wire member being bent and sprung within andacross said hole whereby said heel portion can be snapped intoengagement with either of said shoulders during a longitudinal movementof said wire member.

4:. A scouring device comprising a pad, a handle provided with an axialhole therethrough, having three portions of differing diameters, theintermediate portion being larger than the lower portion and smallerthan the upper portion whereby an annular shoulder is formed at each endof said intermediate portion, a bent wire member within said hole andsprung across the hole, a heel portion at the upper end of said memberadapted for engagement with either of said shoulders and a hook portionat the lower end of said member protruding below said handle and adaptedfor engagement with said pad.

5. A scouring device having a handle with an axial hole therethrough,having three portions each of a greater diameter than the portion belowit, thus forming two annular ledges within said hole, a wire member anda cap on one end, a hook on the other end of said wire member, and aheel portion on said wire member below said cap, said wire member beingsprung across said hole and adapted to have said heel snap intoengagement with either of said ledges during an upward longitudinalmovement of said Wire member within said hole. v
